EXPLOSION-MOTOR.

. To all uihom it may concern:

Be it known that I, CHARLES HENRI CLAU- DEL, citizen of the Republic of France, re-

' siding at 41 Rue des Arts, Levallois Perret,

Seine, in the Republic of France, have invented new and useful Improvements 1n Explosion-Motors, of which the following is a specification.

This invention relates to improvements in explosion motors.

When an'explosion motor is fed by means whereby reduced speedsware obtained by reducing the amount of mixture admitted lowering of the compression results which causes a fall in the power which becomes greater as the motor runs slower.

When such a motor is fed with heavy fuels it. generally happens that difficulty is found in obtaining regular running at slow crank pin traverses the arc B E, the piston speed.

The present invention comprises means whereby when the admission of the gases is reduced by operating a throttle or similar member the apparent compression in the combustion chamber lncreases or in any case diminishes less rapidly than usual.

In the annexed drawing, is represented by Way the invention -Figure 1 is a diagrammatic view of an example of the application of the invention to a four stroke motor.

Figs. 2 and -3 are diagrams showing the variation of regulation which can be obtained. V

, Referring to Fig. 1 it can be seen that the admission valve 1 is connected to the carbureter or vaporizer 3 bymeans of a tube 10 in which is arranged a throttle valve 2 for regulating the speed of the motor.

The throttle valve 2 is operated by means of a controlling lever 15 keyed on a shaft 16 carrying a lever 13 which may actuate an arm 17 secured on the axis'of the throttle valve, To the lever 15, is also connected a short connecting rod 18 and,-fulcrumed on the end of thelattenis a wedgeshaped' pawl 4 which is placed between the cam 5 actuating the admission valve 1 and the valve stem. The wedge or pawl 4 has aninclined bottom face 4* which is acted upon by the boss 5 of the cam and a reversely sloped projection 4 which rests upon a circular boss or hub of the cam when the wedge is not lifted by Specification of Letters Patent.

of example a form of construction of Patented June 1?, rare.

Application filed November 14, 1917. Serial ,No. 202,021.

I said cam. The part 4 has for its purpose to reduce the extent of the oscillating movement of the. wedge about its axis and reduce the noise. I

\Vhen the lever 15 is swung in the direction of the arrow to run at slow speed, the wedge his advanced under the valve stem and the face 4* of the wedge being inclined as shown, the boss 5 of the cam will leave said face sooner whereby the admission valve will be closed sooner than in normal operation. If for instance in normal running the admission valve was open while the crank shaft pin is traversing the arc F E (Fig. 2), the arrangement may be such that the admission be cut off, at slow speed, for

instance at point e near the lower dead point B, the opening of admission then taking place at f. In normal. running, when the forces the fresh gases back into the feeding pipe 10,- which is objectionable and compression is effected over the are E A only while in slow speed running, owing to the arrangement described, the compression is effected for instance over, the whole are e A 2'. e. is practically maximum. The working at slow speed is thus facilitated and improved.

tom face 7 of wedge 7 which cooperates with the cam is inclined in thesame direction as the face 4 of-the wedge 4: so that when the lever 15 is operated to run at slow speed, the wedge 7 isadvanced under the stem of the valve 6 and the boss 8 of the cam 8 leaves the face 7 sooner whereby the exhaust valve is closed sooner than in normal running. If, for instance, in normal operation, the exhaust valve was opened in the period A B (Fig. 3), the arrangement described may be so constructed that the said valve 'be closed at H or even at D, the opening taking place at G or C, respectively. By means of the advanced clo sure of the exhaust valve, the exhaust gases are partially retained in the working cylinder whereby the cylinder at the end of the completely and the next compression opera-' tion. is improved.

The operation of the -motor could also be improved by a throttle 9 mounted-in the outlet pipe 11 for the exhaust gases and connected, for instance to an extension 19 of the lever 19 through an arm 22, or operated ill-1- dependently but in such a way that when the admission is reduced the. sectional area of the passage for the evacuation of the burnt gases will also be reduced. In the latter case it will be advantageous to place the gas throttle beyond the heating conduit 14 of the carbureter in order that during running at slow .speed the heating will be the maximum.

I It is understood that the devices described i above and'shown'in the drawing are given by way of example and, that without depart ing from the invention the arrangement of the various members of the operating mechanism can be modified as may be required.

Having now described my invention, what Iclaim as 'new and desire-to secure by Letthrottle valve mounted, in the suction-pipe,
